Brief Summary

The co-ordination and control of body segments are integral in providing and maintaining postural stability. It is widely accepted that attentional demands for postural control are placed upon the individual, but these vary according to the nature of the task, the age of the individual and their postural stability. It is thought that divided attention (a technique whereby two tasks are performed at the same time whilst rapidly switching attention between the two tasks) is commonly used when multi-tasking. Divided attention may have important clinical implications to falls risk, in that older adults that experience falls have increased difficulty in switching attention between tasks such as walking and talking. Dual tasking paradigms which present postural and cognitive tasks are often used to test attentional demands for posture control and interference between the two tasks. At present it is not known what impact balance confidence, sleep, activity levels or cognitive ability impact on a person's ability to multi-task when performing complex walking tasks that reflect the complexity of mobilising in real-life situations.

Outcome Measures

Primary Outcomes (1)

• Functional Gait Assessment

  The primary outcome is the Functional Gait Assessment which is a 10-item test that assesses performance on complex gait tasks (i.e. walking with head turns, stepping over an obstacle or stopping and turning). Scores range from 0 to 30. The highest score is 30 and greater outcomes are indicative of better performance while lower scores are indicative of poorer performance. The Functional Gait Assessment has been validated in healthy people, older adults with a history of falls and balance impairments, and people with a vestibular disorder. The minimal detectable change for Functional Gait Assessment is reported to be 6 points in persons with balance and vestibular disorders. Scores ≤22/30 identify fall risk and are predictable of falls in community-living older persons within 6 months.

Interventions

Single testing session OTHER

All participants that meet the inclusion criteria, will have to attend the research laboratory at Centre for Human and Applied Physiological Sciences, Shepherd's House, Guy's Campus, King's College London, SE1 1UL to be assessed in a single testing session. The testing session will require them to complete some questionnaires regarding balance confidence, psychological state, sleep and physical function and to undertake some simple tests of cognitive function. They will also undertake a brief dynamic balance assessment and the dual-task gait test. The dual-task component involves two cognitive tasks (a numeracy and a literacy task) or auditory task. The gait test will be performed separately and then together with each of two cognitive tasks or auditory task. On the day, after the testing, each participant will, also, be provided a physical activity monitor (accelerometer-AX3) to wear on their wrist for 24 hours a day, seven days a week without taking it off.

• Purpose: SCREENING
• Intervention Model: SINGLE GROUP
• Sponsor Type: OTHER
• Responsible Party: SPONSOR

Model Details: 100 healthy participants aged between 18-80 years old are recruited for this study. All individuals that express interest in this study, will be provided with a Participant Information Sheet (PIS) either by email or hard copy by post. All prospective subjects will be screened for matching of inclusion criteria. After a potential participant contacts the PhD student, Ms Viktoria Azoidou, regarding his/her interest in participating in the study, the person will be asked to complete the screening questionnaire via telephone or email as per each individual's preference regarding eligibility criteria. If after screening, a potential participant meets the eligibility criteria, an appointment will be arranged to discuss any concerns or answer any questions participants may have regarding the PIS, then sign the written consent form and be assessed attend the research laboratory for the single testing session.
